bq. Jimmy Xiang wrote:
bq. To delete a family, you don't specify the qualifier. To delete a only one version of a column, you sepcify the family, qualifer, timestamp, and set oneVersion to true.
bq. To delete all version of a column, you specify the family, qualifier
bq.
bq. What do you mean a column that has no qualifier? Are you referring to Delete.deleteColumns(family, qualifier, timestamp), and qualifer = null?
bq.
bq. Michael Stack wrote:
bq. Yeah. You can put a value at row, family, null qualifier, ts. You can also delete it (might not be a good idea but you can do it).
In this case, all columns in the family for this row will be deleted, right?

bq. This is used as a default region. If you have multiple Gets on the same region, you don't have to specify it every where.
bq.
bq. Michael Stack wrote:
bq. Could we just have it out here as a param on the get and not in the Get object? Will that work (I think I understand why Result needs it internal to cut down on objects we need to support multiresponses)
Sure, I can do that for get.

bq. The interface is kind of similar, but very flexible. Any problem with that?
bq.
bq. Michael Stack wrote:
bq. On 'Any problem with that?', no. Just trying to avoid redundancy that makes the Interface imprecise and therefore hard to grok.
I see. I will remove the region from Get. It is ok not to support multiGet, right?

bq.
bq. Jimmy Xiang wrote:
bq. That's to support multiple Get requests in one call. Each Get request can have its own region. If all Gets are for one region, the caller can specify the region in the request level.
bq.
bq. Michael Stack wrote:
bq. I see specifying the region name in this GetRequest but not sure about why we'd have region in the Get object itself if we are doing it here on the invocation. Seems like the two contend?
I will remove it from Get object to avoid confusion for now.

bq.
bq. Jimmy Xiang wrote:
bq. In the multi call, they mix many requests together. However, they don't retrieve the response in order. They retrieve the response based on the region name.
bq. In this case, I'd like the server to return the region name. This is optional. In most call, it is not used.
bq.
bq. Michael Stack wrote:
bq. So you are doing this so you have to create less objects? So you can avoid MultiResponse with its regionname to responses?
Right. Should I create a separate message for MultiResponse?

bq.
bq. Jimmy Xiang wrote:
bq. This is for the exist() call. In this case, the caller doesn't care about the result. They just want to know if the row is there. It is not special handling of an attribute.
bq.
bq. Michael Stack wrote:
bq. The current implementation actually does the fetch and in the client checks it null or not IIRC? Or is it all serverside? So you add this to the Get so you don't have to do the exists call? You can implement it w/ the addition to Get?
It is all in the server side. I can do it in the client side and remove it. That means some wasted network bandwidth. What do you think?

bq.
bq. Jimmy Xiang wrote:
bq. The same reason as for Get. It is used as a default region in case all/most mutates are for a same region.
bq.
bq. Michael Stack wrote:
bq. Having 'default' region doesn't sound right, even if you are trying to be flexible.
I see. For get, we put the region in the request level. I prefer to do the same for mutate. But if we put the region in request for mutate, we have to have a several
call to handle RowMutations in the same call. I can try to handle RowMutations in the multi call.
Another thing is that, if we put the region in the request level, do we need to support multiple Get per get request? How about multiple Mutate per mutate request?

------------------------------------
But for proto files, other projects depend on protoc, for example HADOOP/HDFS. We are moving towards pb, protoc dependency should be fine.
I can try to setup a temp protoc dynamically.

Enis Soztutar commented on HBASE-5619:
--------------------------------------
I think for compiling protoc installation should not be a dependency. Why don't we add the generated java files to the source tree, so that only if you change the protoc definitions, you would have to recompile the .proto files. As far as I know, this is how it is done for thrift dependencies in other projects.

My guess is that this region in a Scan won't do you any good. The client figures where the Scan is at any one time and what region it should be on. There is probably no value having this in the Scan.

bq. What'd do you think? To me, it is fine either way. However, if we are going to replace HRI with the protobuff later on, it may be better to put them together.
bq.
bq. Michael Stack wrote:
bq. Hmm. Moving out these flags changes the current 'model' but in a direction we should be headed in. The split/offline stuff were stuffed into HRI in the first place just because this was an easy way to pass these transient states around in hbase; they also are less important now in HRI though still depended on when we scan meta IIRC. Its probably better to evolve toward an HRI that is immutable once made. So I'd be down w/ moving them out but its up to you. It might be easier on you achieving parity w/ first commit of pb work if the pb classes are like the internals they will be feeding into.
bq.
bq. Jimmy Xiang wrote:

That might be easiest. I think yeah, they don't really belong in here and we've made some work undoing their need to be i here but lets do that in another issue....

Then I was wrong in my supposition. Lets do what you suggest, an actual return with a response w/ some value in it.

I think we do what is currently there first and then after pb goes in, work on changing it. This extra flag in Get is fine (Check exists could be done as a filter if we were going to redo). Lets add it to make Get flexible as you suggest we do elsewhere in these remarks.

On 'Should I create a separate message for MultiResponse?', I defer to you. You have your head in this stuff. It sounds cleaner to me having the Mutate being one message and then Mutate+regionspec be a new Message that is used trying to do Multi stuff but you are closer to what is going on here.

We should support multiget, yes. Do you have to make a new message to do that if you remove the regionspec from Get? If so, maybe that is ok? If not, i'm fine w/ it as optional regionspec in Get. I think it would be fine to purge regionspec from the Get, Put, Delete, objects and then add messages to support multactions. Up to you. Just doc it and be consistent (smile).

bq. Another thing is that, if we put the region in the request level, do we need to support multiple Get per get request? How about multiple Mutate per mutate request?
On "I can try to handle RowMutations in the multi call.", good. So, we won't do multiple calls to do many?

I used to put these transient parameters in the protobuff RegionInfo as well. However Todd thought it's better to put them outside.
What'd do you think? To me, it is fine either way. However, if we are going to replace HRI with the protobuff later on, it may be better to put them together.

I though about this. I added documentation to RegionClient.proto. For methods in RegionAdmin, the method names seem to be very clear. I will take a look again and document where confusing/misunderstand could arise.

Some call expects a region name, some call expects an encoded region name. With a specifier, we can handle both.
Encoded region name works only if the region is on-line. If we can't find the region based on the specifier, a region not found exception will be thrown.
So we can simplify the request a little bit since we don't have to ask for region name, and encoded region name, and check only if one is specified.
I will add a comment for it.

In the multi call, they mix many requests together. However, they don't retrieve the response in order. They retrieve the response based on the region name.
In this case, I'd like the server to return the region name. This is optional. In most call, it is not used.

It is used when the caller wants the existence only, not the result itself.

Sometimes, for some action, for example delete, they don't care about the result. They just want to know if the action is processed or not. This is for this kind use case.

That's to support multiple Get requests in one call. Each Get request can have its own region. If all Gets are for one region, the caller can specify the region in the request level.

The interface is kind of similar, but very flexible. Any problem with that?

This is used as a default region. If you have multiple Gets on the same region, you don't have to specify it every where.

It is for checkAndPut and checkAndDelete.

Similar to Gets, I'd like to make the interface flexible. Sounds you prefer to have simple interface instead, right? That means we may have to have too many methods. For java interface, it is ok and preferred to have many methods. But for RPC, I think it is better to have fewer and flexible methods.

To delete a family, you don't specify the qualifier. To delete a only one version of a column, you sepcify the family, qualifer, timestamp, and set oneVersion to true.
To delete all version of a column, you specify the family, qualifier
What do you mean a column that has no qualifier? Are you referring to Delete.deleteColumns(family, qualifier, timestamp), and qualifer = null?

The same reason as for Get. It is used as a default region in case all/most mutates are for a same region.

Yes, it is the first region.

It is the region where the row is on. The row is in line 277.

Yes, this is for Region protocol, not client API. You need to specify for which region this action will be executed on, right?

Excellent.
It looks like we can commit this w/o breaking whats currently there?
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13813>
What did we figure on the package name? Shouldn't it agree w/ the dir that holds the .proto files at src/main? Currently one is protobuf and the other is proto.
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13835>
What are these two booleans broken out? Aren't they in they attributes of HRI already? Why repeat them?
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13836>
Good. Its kinda dumb the way our HRegionInterface is now where it has an override, one that takes single family and another that takes an array. Thanks for collapsing.
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13837>
Should we be repeating the API documentation that is up in the HRegionInterface that this .proto replaces here? If its not here, where will it be? Not all of the javadoc should make it over -- the stuff that says nothing shouldn't but some is of worth. What you think?
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13838>
Again, thanks for doing the work collapsing the overrides that are up in HRegionInterface.
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13839>
Isn't the response currently a void? And isnt' flush async (IIRC). If so, under what circumstance would we be able to fill out this response?
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13842>
WALKey maps to HLogKey? Maybe add a comment to this effect?
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13846>
Good. I like this method name better. Should be a comment which points back to the old name? Or what you think?
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13847>
Yeah, this proto is missing commentary. I mean, the return here should be explained?
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13850>
This will for sure grow w/ time.
src/main/proto/RegionAdmin.proto
<https://reviews.apache.org/r/4054/#comment13855>
Nice. So you are splitting HRegionInterface into admin and client? Good.
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13862>
This is new? Being able to do this? How will it be used?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13863>
This is new feature on get? Or just special handling of an attribute?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13864>
We don't have this in the java Result. I don't understand why this is making its way into the object.
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13865>
ditto
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13866>
what is processed?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13867>
Why we need to add a region to the Get even optionally?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13868>
Why is the Get polluted by multiGet stuff?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13869>
I thought we could set this into the Get above? Why have it here as separate param?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13870>
Good stuff
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13872>
This is a new feature?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13881>
A type rather than have the mutation type specified as a subclass?
A mutate is a delete or put?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13882>
Again, does it make sense having this in here? I mean regions come and go -- e.g. split -- so you could have reference to non-existent region. This stuff of tying a mutation to a particular region should be done external to the mutations themselves?
Is this trying to do multiaction? Maybe that should be a message apart from mutate? The new message would have region name and the mutate?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13885>
What is this implementing from current Delete? The delete family?
This is returned to the client?
How do we do a column that has no qualifier? Thats possible in hbase.
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13890>
Yeah, why have regionspecified in the mutate if you are going to provide it as a param too?
src/main/proto/RegionClient.proto

Why this when regions can change. Also, a Scan can traverse many regions so what is the regionspecifier referring to? The first?
src/main/proto/RegionClient.proto
<https://reviews.apache.org/r/4054/#comment13899>
Is this supposed to be row specifier?

ditto

Does this belong here? You provide it as a param when making the request.

I like the idea of checking in the generated protobufs files. They'll change rarely. Let the fella who generates them have to worry about his protoc setup (This is what we do now for thrift and avro?)

So, can an open scanner return results? Curently returns scanid only. This looks like it could return scanid AND first set of results. That'd be cool.

bq.
bq. What'd do you think? To me, it is fine either way. However, if we are going to replace HRI with the protobuff later on, it may be better to put them together.
Hmm. Moving out these flags changes the current 'model' but in a direction we should be headed in. The split/offline stuff were stuffed into HRI in the first place just because this was an easy way to pass these transient states around in hbase; they also are less important now in HRI though still depended on when we scan meta IIRC. Its probably better to evolve toward an HRI that is immutable once made. So I'd be down w/ moving them out but its up to you. It might be easier on you achieving parity w/ first commit of pb work if the pb classes are like the internals they will be feeding into.

bq. I though about this. I added documentation to RegionClient.proto. For methods in RegionAdmin, the method names seem to be very clear. I will take a look again and document where confusing/misunderstand could arise.
I'd be fine w/ the doc being sparse but there are a few cases where doc is necessary; e.g. the one I cite above.

Does that imply a synchronous call? I thought flushCache just queued the flush then returned to the client w/o actually waiting on flush to complete.

bq. Some call expects a region name, some call expects an encoded region name. With a specifier, we can handle both.
bq. Encoded region name works only if the region is on-line. If we can't find the region based on the specifier, a region not found exception will be thrown.
bq.
bq. So we can simplify the request a little bit since we don't have to ask for region name, and encoded region name, and check only if one is specified.
bq.
bq. I will add a comment for it.
ok

bq. This is for the exist() call. In this case, the caller doesn't care about the result. They just want to know if the row is there. It is not special handling of an attribute.
The current implementation actually does the fetch and in the client checks it null or not IIRC? Or is it all serverside? So you add this to the Get so you don't have to do the exists call? You can implement it w/ the addition to Get?

bq. In the multi call, they mix many requests together. However, they don't retrieve the response in order. They retrieve the response based on the region name.
bq. In this case, I'd like the server to return the region name. This is optional. In most call, it is not used.
So you are doing this so you have to create less objects? So you can avoid MultiResponse with its regionname to responses?

bq. That's to support multiple Get requests in one call. Each Get request can have its own region. If all Gets are for one region, the caller can specify the region in the request level.
I see specifying the region name in this GetRequest but not sure about why we'd have region in the Get object itself if we are doing it here on the invocation. Seems like the two contend?

Could we just have it out here as a param on the get and not in the Get object? Will that work (I think I understand why Result needs it internal to cut down on objects we need to support multiresponses)

bq. Similar to Gets, I'd like to make the interface flexible. Sounds you prefer to have simple interface instead, right? That means we may have to have too many methods. For java interface, it is ok and preferred to have many methods. But for RPC, I think it is better to have fewer and flexible methods.
'But for RPC, I think it is better to have fewer and flexible methods.' Fair enough. Would like to make it just flexible enough and no more (smile). Needs documentation too else fellas like me will come in and get wrong impression on whats going on.

bq. What do you mean a column that has no qualifier? Are you referring to Delete.deleteColumns(family, qualifier, timestamp), and qualifer = null?
Yeah. You can put a value at row, family, null qualifier, ts. You can also delete it (might not be a good idea but you can do it).

Yes. I got into habit of complaining about the region specs. They make sense when they are params. Its regions internal to Get, etc., that causes me difficulty.

@Jimmy Is there a maven plugin for protoc so folks don't have to install it? At least, we should be checking for its presence and complaining w/ a pointer to a how-to-install doc if not present? Is that possible?

They both should be either there, or not. I can add an optional message UUID, which should have both listSigBits and mostSigBits. How is that?

For repeated parameter, for example, region, the generated method is something like getRegionList(). So it may be better to use singular for parameters.
For similar reason, I did the same for method name. Another reason for that is, in the future, we may use this method to just get one online region given a region name.
This way, we can limit the number of methods.

That's right. But we can still make increment a mutation, in protocol buffer. Since Increment doesn't extend Mutation, it is a little bit different to map an Increment to a Mutate.
So we don't have to have a separate method for Increment.

Increment is treated as a Mutate, so it is needed.

I see. Let me enhance the doc. The reason for that is Exec is called for a region. In the request level, there is a default region. Users can specify different region for each individual Exec.

------------------------------------
@Stack, so far, I could not find a good protoc maven plugin. I don't remember I tried to install it on my Ubuntu.
That's the download site for protobuf compiler: http://code.google.com/p/protobuf/downloads/list
But for Linux, I think it is easy to install with rpm/apt-get.

Oh my, it's just that review board sucks, it's still showing the file as being added when comparing r1 and r4, even though the file is no longer in r4.

stack updated HBASE-5619:
-------------------------
Attachment: 5619v6.txt
This is Jimmy's patch with a package.html added at o.a.h.h.protobuf to say whats going on in the package and then a README at src/main/protobuf with directions and a bit of script (from pom.xml amended) on how to regen the classes if you make changes to definition files.
I tried to find a way to add an apache license to the generated files -- its probably not necessary... they have headers which say they are generated files -- and a bit more doc on where the proto files are, etc., but I couldn't figure how from reading protobuf documentation.
Also excluded new generated files from findbugs report

bq. I was thinking to set it if the HRegion.flushCache call returned true. It is just informational.
bq.
bq. Michael Stack wrote:
bq. Does that imply a synchronous call? I thought flushCache just queued the flush then returned to the client w/o actually waiting on flush to complete.
I checked the code and it seems that flushCache is a synchronous call. Should we make it async? If so, I can make flushed to queued.

bq. I used to put these transient parameters in the protobuff RegionInfo as well. However Todd thought it's better to put them outside.
bq.
bq. What'd do you think? To me, it is fine either way. However, if we are going to replace HRI with the protobuff later on, it may be better to put them together.
bq.
bq. Michael Stack wrote:
bq. Hmm. Moving out these flags changes the current 'model' but in a direction we should be headed in. The split/offline stuff were stuffed into HRI in the first place just because this was an easy way to pass these transient states around in hbase; they also are less important now in HRI though still depended on when we scan meta IIRC. Its probably better to evolve toward an HRI that is immutable once made. So I'd be down w/ moving them out but its up to you. It might be easier on you achieving parity w/ first commit of pb work if the pb classes are like the internals they will be feeding into.
Ok, I can move them back. We can get back to this when time comes.

bq. Similar to Gets, I'd like to make the interface flexible. Sounds you prefer to have simple interface instead, right? That means we may have to have too many methods. For java interface, it is ok and preferred to have many methods. But for RPC, I think it is better to have fewer and flexible methods.
bq.
bq. Michael Stack wrote:
bq. 'But for RPC, I think it is better to have fewer and flexible methods.' Fair enough. Would like to make it just flexible enough and no more (smile). Needs documentation too else fellas like me will come in and get wrong impression on whats going on.
Sure. I will make it simple for now. We can enhance if requirements come up.

--------------------------------------
I was suggesting adding the generated files under src/, and adding the runtime protobuf dependency in maven. But if it won't work, we can go with requiring protoc. Dynamic installation will be a little bit overkill.

I'm looking at differences between r1 and r4 and I don't see anything new in HRegionProtocol.proto ..?
pom.xml
<https://reviews.apache.org/r/4054/#comment13781>
Can you please kill all the trailing whitespaces while you're at it?
pom.xml
<https://reviews.apache.org/r/4054/#comment13779>
Just do "if which cygpath 2>/dev/null" instead of doing it on 2 lines and testing $?
pom.xml
<https://reviews.apache.org/r/4054/#comment13782>
Just do "for PROTO_FILE in $UNIX_PROTO_DIR/*.proto", I don't think the "ls" is really necessary here.
src/main/proto/HRegionProtocol.proto
<https://reviews.apache.org/r/4054/#comment13783>
I'm not seeing that you added it.
